GEORGE HOWLETT DAVIS, OF WEST ORANGE, NEW JERSEY.

MUSIC-ROLL.

' Application filed February 24, 1915.

To all whom it may concern:

Be it known that I, GEORGE HowLnTT DAVIS, a citizen of the United States, residing in the town of West Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Music-Rolls, of which the following is a specification.

In my prior patent application, Serial No. 867,775, filed October 21st, 1914, I have illustrated and described what I termed as an attachable music roll; that is to say, a perforated music roll which has an attaching hook at its rear end, and the usual attaching ring at the front end so arranged that the hook fastener may be connected to the ring fastener of an ordinary music roll, and the attachable music roll wound upon a spooled music roll, the purpose being to connect two or more such rolls in tandem and wind the same upon a spool so that the en tire collection of rolls may be mounted in a player instrument and played consecutively in the ordinary way. The result of such structure is to very materially reduce the cost of music rolls inasmuch as the cost of the spool constitutes a material item in the manufacture.

Mypresent application discloses an improvement upon the structure of the above named prior application, and it has for its object the provision of a substitute for the spool of a music roll, and at the same time the provision of improved attaching devices whereby all of the results accomplished by the structure of my prior application are accomplished by my present improvement.

It consists primarily of a pair of flanged ends, or plugs, to be inserted into the end of a perforated music roll, which has been partially or fully rolled up; these flanged plugs constituting a pair of trunnions or spindles, by which the entire structure may be inserted in the winding devices of a player instrument, and the roll played in the usual manner. The end fastener consists of a very small, but exceedingly stiff wire, looped in the middle to form a ring, with the ends twisted together for a short distance and spread apart T-shaped to be inserted through a slit in the front or pointed end of a music roll which is'then folded over and pasted down to form a flap within which the T end of the fastener is secured. The attaching fastener for the rear end of the following roll is made and secured in the same Specification of Letters Patent.

way, except that instead of forming a ring loop, the wire is bent in the middle into a T head, and then twisted for a short dis tance after which the ends of the wire are spread apart in T-shape to be inserted into a fold or flap upon the rear end of the attachable roll and secured in the manner above described.

The construction of a music roll with the flanged trunnions as above described, possesses the following advantages: First, the cheapness in the cost of manufacture, inasmuch as the flanged heads cost but a fraction of what the older form of spools now costs. Second, the coefficient of expansion of the prior forms of spool and the paper of which the perforated roll is made, are different. This has resulted in the construction of many devices for taking care of the expansion and contraction of the paper due to atmospheric changes, so that the roll, as it is wound upon the spool, will be made to hug the flange of the driving end of the spool in order that it may track properly over the tracker bar of a player instrument. In the present improvement, inasmuch as the flange plugs are secured directly to the paper of which the music roll is made, the extreme ends of the completed roll will vary, in distance apart, in exact accordance with the expansion and contraction of the paper itself, thereby avoiding the necessity of adjusting devices for the spool heads or flanges.

In carrying out my invention, I make use of the structure substantially as illustrated in the accompanying drawings, wherein- Figure 1, illustrates a plan view of a completed roll with the end fastener secured thereto, and with a removable music roll shown as connected to the end fastener. Fig. 2, is a full size, vertical section of the adjacent ends of the music rolls with the end fasteners secured thereto, showing the manner of lapping the front and rear ends of adjacent rolls, the lapping of the label around the ends of the rolls, and the locations of the end fasteners within the folded flaps of the rolls and labels. Fig. 3, is a view of a pair of end fasteners connected and shown detached from the rolls. Fig. 4, is a plan view of the leader, or rear end of the music roll showing the line of the fold and the slit through which the end fastener is inserted. Figs. 5, 6, and 7, are respec tively rear end, side, and front elevations of the left-hand flanged plug. Figs. 8, 9, and 10, are respectively front, side, and rear elevations of the right-hand flanged plug. Fig. 11, is a vertical section of the completed music roll with the flanged plugs inserted, showing the method of attaching the rear end of a music roll to the plugs.

Similar letters of reference refer to like parts throughout the specification and drawings.

In the construction of my improved music roll I provide the two end flanged plugs, 1 and 2, which may be made of wood, a molded composition, or any convenient material suitable for such use. The plug 1, is provided with the conical end socket 3, by which the completed roll may be supported in the player instrument. Next, is the flange 4, which corresponds with the usual flange of a spool; and finally the cylindrical part 5, for insertion into the end of a partially or fully rolled music roll. The opposite plug 2, is the substantial counter part with the flange 1, with the exception that the socket 6, is usually constructed in cylindrical form and is provided with the diametrical driving slot 7, into which the fin of the driving shaft of the player mechanism is inserted when the roll is mounted for playing.

In practice, the method of assembling the parts is as follows: A rotating driving inandrel of substantially the diameter of the plugs 5, is used, upon which the rear end of the music roll R is given a few turns; then glue, or other adhesive material is applied either in spots 8, or in a narrow strip completely across the face of the partially coiled music roll; then the music roll is completely wound upon the mandrel; then the music roll may be removed from the mandrel. The plugs 1 and 2, may be inserted into the tubular roll thus formed, first applying a dab of glue, or other adhesive material, to at least the plug '2, so as to firmly secure such plug to the inner layer or coil of the music roll. The plug 1, may also be secured by the adhesive material to the inner coil of the paper if desired, but this is not neces sary, as in winding up the roll the inner layers of paper naturally coil tightly upon the part 5. Upon completely winding up the roll, and securing the end fastener and label thereto, the roll is finished and ready for boxing and shipment.

The end fastener, as above indicated, consists of a fine, but very stiff wire 9, with a ring formed at 10, and strands of the wire twisted as at 11, while the extreme ends 12 are spread apart in alinement to form a T head. This ring fastener is inserted through substantially the same manner by folding its lower edge over the flap 14;, upon the rear side, and. then pasting the main body of the label. upon the front face of the roll, as shown in Fig. 1. It is understood that a slot 16 is provided in the lower edge of the label 15, through which the ring 10 may be passed. \Vith the flap 14, the fastener 9, and the label 15, thus secured to the leader end of the roll, a firm, effective, and inexpensive end fastener is provided.

The end fastener of the rear end of an attachable roll is secured to the pointed rear end of such roll in substantially the same manner as above described, that is to say, the pointed rear end is folded back as at 17, with the alined ends 12, of the fastener within the fold, and the twisted portion 11 pass ing through a corresponding slot in the roll. The label 18 is folded over the flap 17, and pasted down on the front side of the roll, as shown. lVhen two rolls are to be connected together, the T end 18, of the attachable roll is inserted through the ring upon the leader end of the preceding roll, and the attachable roll is then wound upon the preceding roll and will then be ready for playing. It is understood that a corresponding ring end fastener is secured to the leader end of the attachable roll. lVith this construction, a plurality of rolls may be wound upon a single spool substantially as indicated in my above named prior application, or upon the roll such as described in the present application.

It should be noted that in attaching the plugs 1 and 2, into the ends of the music sheet, only the extreme end of the sheet is secured by glue or other adhesive material, to the cylindrical parts 5 of the plugs 1 and 2, and that several layers,at least two or three, are wound up before the adhesive material is applied at 8, either in spots or in a single narrow band completely across the sheet. By thus connecting the plug 2 to the extreme inner end of the sheet and leaving several layers free to coil upon the cylindrical part 5, as the plugs 1 and 2 are rotated at times when tension is applied to the leader end of the sheet, through the end fastener, the result is that the sheet Will coil tightly upon the cylindrical part 5, of the plugs 1 and 2, and thus firmly hold such plugs in place. The several permanent layers which are coiled upon the cylindrical part 5, of the plugs, make a reasonably firm foundation for the other layers which follow, so that when the music sheet is completely rolled up, the entire structure is quite firm and solid, and may be handled without fear of injury. The resulting structure, therefore, is substantially as illustrated in Fig. 11, so that the completed roll consists of but three parts, namely, a perforated sheet of paper, and the two plugs 1 and 2.

While I have shown the outer ends of the plugs l and 2, as provided with the sockets 3 and 6 with the diametrical slot 7, I do not desire to confine myself to these forms alone, since they are merely illustrative of one of the many forms used for attachment to the player driving and supporting mechanism. It is to be understood that wing pins may be inserted into these plugs if desired so that the rolls may be adapted to any of the forms of driving mechanism for players now in use.

It will thus be seen that I have accomplished all of the objects set forth by a structure at once simple, inexpensive, easy of manipulatiomand not liable to disarrangement or disorder.
